99 MC250 as a good learner trail bike?

[pscook]

My nephew wants a two-stroke trail bike to replace his XR400. Around here we have KDX 200's going for $1200 to $2500, depending on mods and upgrades (and miles/hours). Then there is this example of a decent (at a distance) MC250 http://www.gasgasrider.org/forum/showthread.php?t=13882.

Including shipping, the price works into the KDX territory, tied with a 1995 WR250, and about $500 cheaper than the nearest (reasonable) KTM 250 or 300. What does everyone think of the MC250 for a trail/scrambles bike? Brad is a beginning C class rider, mostly trails until this year. A couple of short scrambles and the Desert 100 (one lap before houring out). So he isn't a fast-class rider. Would the 4-speed gear box be a hindrance to someone learning to ride a two stroke? Any reason to hold out or wait for a better bike? Any other options or ideas?
